Best Investment Property HELOC Program on One Rental to Buy the Next

The Quick Read: An investment-property line on your existing rental can fund the next down payment, but across Lendmire’s wholesale network it caps at 70% CLTV, needs a 700 credit score, and must be titled to you or your living trust; the strongest setup pairs it with a rent-based DSCR purchase loan. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.

• The best program for your situation depends on how much equity sits above your first mortgage and who holds title.
• Two separate approvals are involved: one for the line on rental one, and one for the loan on rental two.
• An investment line tops out at $500,000, and at least 75% of it is drawn at closing.
• The line’s payment floats and sits outside the DSCR ratio, so you have to stress-test it yourself.

Can One Rental’s Equity Really Fund the Next Purchase?

Yes, when three things line up: enough equity above your first mortgage, an eligible title, and a purchase lender that accepts the source of your down payment. The line is a second loan on rental one. The proceeds are yours to spend, usually on the next down payment.

Availability is the first hurdle. NerdWallet notes that not every lender offers a line on an investment property, and that requirements are strict. Experian agrees that these lines are generally harder to qualify for than a line on your home.

That scarcity is why a broker matters here. Lendmire works with a network of wholesale HELOC lenders and matches the property, equity, credit, and title to the program that fits. No single lender’s page can compare programs for you. Lendmire is a broker, not the lender, and every figure below is subject to lender guidelines and full file review.

How the Two Approvals Work

You are applying for two separate loans. They have different collateral, different tests, and different ways to fail.

You cannot put the line on the property you are buying, because you do not own it yet. That is why the line comes first and is built around the rental you already hold.

The purchase side is a DSCR loan, which qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. DSCR means debt service coverage ratio: monthly rent divided by the property’s full monthly payment (principal, interest, taxes, insurance, and any HOA dues). Our complete DSCR loans guide walks through that test in full.

What the Investment Line Looks Like on Our Network

These are the parameters we see for investment-property lines. They apply to investment properties only. Lines on a primary home follow different tables.

• Leverage: 70% CLTV, and nothing higher on an investment property.
• Credit: a 700 minimum. Both 720-plus and 700-plus files reach the same 70%, so a higher score buys eligibility, not extra leverage.
• Size: $25,000 up to $500,000. Lines above $500,000 are for primary residences only.
• Structure: a standalone line in first or second lien position, with a 5-year interest-only draw and a 25-year repayment period. The pricing floats through both periods and never converts to fixed.
• Draw at closing: at least 75% of the line is drawn when you close.
• Later draws: typically a $1,000 minimum.
• DTI: 50% maximum, tested on the interest-only payment at the full draw.
• Valuation: lines of $500,000 or less ordinarily use an automated valuation with no traditional appraisal. You can still request a full appraisal.

Market surveys differ. On our network, an investment line is 70% CLTV, period.

Property types matter too. Single-family, 2-4 units, PUDs, townhomes, and condos (including non-warrantable) are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not offered. Investment-line placements run in 16 full-service states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, and WA.

Which Program Fits Your Situation?

The best program for your situation is the one whose title, leverage, and credit rules match your file. Here is how that sorts out in practice.

A line on your primary residence has higher ceilings, reaching 90% CLTV at a 720-plus credit profile. It also puts your home behind your rental purchase. That is a real tradeoff, not just a leverage number.

The Sequence, Step by Step

1. Check title first. The line must be held by you personally or by your revocable living trust. If the rental sits in an LLC, stop here.

2. Measure equity. Take 70% of the property’s value, then subtract your first mortgage balance. That is your ceiling before the credit and DTI tests.

3. Size the line to the need. Because at least 75% is drawn at closing, a line sized well above your down payment means you carry interest on money you are not using.

4. Line up the purchase lender before you draw. Ask whether they accept a documented draw as the down payment.

5. Close the line and move the funds. Park the draw in a clearly labeled account. A clean paper trail helps the purchase file.

6. Buy the property. The DSCR loan is sized on the new property’s rent against its own payment.

7. Plan the exit. The line’s pricing floats, so decide early whether you will pay it down or refinance rental one to clear it.

BiggerPockets describes investors using these lines as short-term money, then recycling the funds into the next deal. That is a sound frame. The line is a bridge, not permanent debt.

A Worked Example

Run the numbers on a modeled setup. These are assumptions, not market data.

Say rental one is valued at some amount, and your first mortgage balance equals 45% of that value. At a 70% CLTV ceiling, you have room for up to 25% of the value in a line. That is before credit, DTI, and the $500,000 cap.

Now say rental two is priced about the same as rental one. A DSCR purchase loan typically runs 75% to 80% LTV on a purchase, meaning 20% to 25% down. A 25% line covers the down payment at the 25% end, but not closing costs or reserves. Those come from your own cash.

Here the file looks healthy on paper. Assume rental two rents for enough to clear roughly 1.2x on its own payment. The lender sees solid coverage. But that ratio counts only rent against the property’s payment. The line’s payment, repairs, vacancy, management, and utilities all sit outside it. Clearing 1.00 is not the same as positive cash flow.

Now stress it. Rental two sits empty for a stretch. Rental one’s first mortgage, the line’s payment, and rental two’s payment are all due. And because the line’s pricing floats, the cost of the line can move against you at the same time. Before you draw, test the file with rental two vacant and the line fully drawn.

Will the Purchase Lender Accept Borrowed Down-Payment Funds?

It depends on the lender and the file. A purchase lender may accept a documented draw, may limit the borrowed share, or may want some of the down payment from unborrowed funds.

A DSCR purchase loan does not run your personal DTI through the same filter a conventional loan does. That helps. But the lender still asks where the money came from, and your reserves still matter. Reserves commonly run around 6 months of PITIA on a DSCR purchase, though they vary by lender, leverage, loan size, and transaction type. PITIA means principal, interest, taxes, insurance, and association dues.

One investor commenter on BiggerPockets says banks usually dislike a down payment that comes from a line and may add it to your DTI. That is one anecdote, not a rule. The fix is the same either way: ask first, and match the program to the answer.

For leverage, most DSCR purchase files land at 75% to 80% LTV. Select programs reach 85% LTV with roughly a 700-plus score. Coverage of 1.00 is where select programs start, and stronger ratios open better terms. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Most programs want a score around 660, and a 620 floor exists in parts of the network. Loan sizes run up to $3,000,000 on standard programs (smaller balances available through select lenders).

Where the Rule Breaks

LLC title. The sharpest difference from a DSCR loan: an LLC, corporation, partnership, or land trust cannot hold title on the line. If your rental is already in an LLC, you need a vesting change or a DSCR cash-out refinance instead. Anecdotes on BiggerPockets go both ways on whether entity-held rentals can get lines, which is why lender fit matters.

Credit at 650. The line floors at 700 on investment property, and there is no tier below it. A DSCR cash-out can still work at lower scores in parts of the network.

Need above $500,000. An investment line stops at $500,000. Anything larger needs a different structure.

Portfolio limits. A borrower is limited to three lines, and an owner of more than 15 financed properties is not eligible.

Credit events. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Investment files follow a 7-year path for foreclosure and 4 years for a deed-in-lieu, pre-foreclosure, or short sale.

Foreclosure exposure. The rental is collateral. Experian lists foreclosure risk as a core downside, and a line on a vacant, cash-strapped property is where that bites.

Line or DSCR Cash-Out Refinance?

The choice comes down to how much equity you need and how much your first mortgage is worth keeping.

On a standard rental, DSCR cash-out refinances top out around 75% LTV across most of the network, with about 6 months of seasoning as the common expectation. If your first mortgage is cheap and you need a modest sum, the line protects it. If you need a large sum, or the title is in an LLC, the cash-out usually wins.

On a long hold, one more point. Borrowing the full down payment means you finance close to 100% of the purchase across two loans. Many investors accept that for a deal with a clear exit, such as a refinance after improvements. For a plain buy-and-hold, the math needs more cushion.

Key Terms Defined

HELOC: a home equity line of credit, a revolving loan secured by property you already own.

CLTV: combined loan-to-value, which adds every loan on the property and divides by its value.

Lien position: the order in which lenders get paid if the property is sold; a first lien is paid before a second.

Draw period: the stretch when you can borrow from the line, paying interest only on this program.

DSCR: monthly rent divided by the property’s full monthly payment.

Vesting: how title is held, such as in your name, a revocable living trust, or an LLC.
